The goal of this project was to determine the optimal conditions for sugar extraction from malt bagasse.Our collaborators in Unicamp treated malt bagasse using a semi-continuous flow reactor at two flow rates, 10 mL/min and 20 mL/min, and at four temperatures each, 140°C, 160°C, 180°C and 210°C. We also treated malt bagasse using a batch process at 140°C, 160°C, and 180°C.Their analysis of the extracted liquid samples suggested that higher flow rate and temperature generated greater sugar yield.To confirm their results, the solid residues were analyzed using Fourier Transform Infrared Spectroscopy and Thermogravimetric Analysis to evaluate their compositions. We concluded that the highest amount of hemicellulose was extracted at the flow through process at a 20 mL/min flow rate and 210°C.
